A note for your reading
The description attached to a record can become part of how someone judges it. Imagine asking readers to assess the same passage with different author labels. If their judgments changed, the comparison would raise a question about the influence of those labels. It would not show which judgment was correct. To examine a review process, ask what information the evaluator saw and when it was revealed. Keeping the record separate from expectations about its origin can help clarify what the evaluation is actually responding to.
Keep asking / 03
Three questions to carry forward
- What information about the record's origin was visible during the evaluation?
- How could the evaluation compare judgments made with and without identifying information?
- Why would a change in judgment leave the record's actual quality unresolved?
